Tuberculosis can be regarded as a global pandemic with almost 9 million new cases and approximately 2 million deaths each year. (1) An estimated one-third of the population of the world is infected with Mycobacterium tuberculosis, and the resultant disease represents a major public health problem. (2) Endemic infection is a major contributor to the annual death rate across the globe. The high morbidity and mortality of tuberculosis is the source of major medical and social problems, especially in developing countries.
It is ranked as the seventh highest cause of morbidity worldwide, and ranks even higher in emerging nations. (3,4)
